The NTSB's narrative final · quoted from the NTSB record
The flight instructor stated that the approach during the student’s fifth landing became unstable. The airplane was near the runway edge when the instructor told the student pilot to initiate a go-around. The instructor said that full engine power was applied, but there was no major increase in thrust. The flight instructor then took the controls from the student but was unable to regain control of the airplane. The airplane then impacted the ground alongside the runway and sustained substantial damage to the wings. Postaccident examination of the airframe and testing of the engine revealed no mechanical anomalies that would have resulted in the engine not producing full power.
